Step 6: By July numerous pest are active in their life cycle.

One, which irritates many homeowners, is the Lace Bug. Lace Bugs feed on ornamentals such as Azaleas, Pyrancanthas, Cotoneasters and Andromedas as well as Sycamore and Oak trees. Lacebugs predominately feed on the underside of leaves causing whitish-yellow flecks called stipples on the upper surface. This damage is the first sign of an infestation. Lacebugs will also produce black fecal spots on the underside of the leaves. The adult only reaches 1/8’ in size. As is implied by the name, the wings of the adult are delicate and lacelike. They are usually clear with black markings. Most species have multiple generations in a year. A forceful thorough spray with a systemic is the only way to get good control. Although this pest can be stubborn it can also be avoided. Azaleas planted in full sun is a sure way for lacebugs to visit your property.
